1, low-temperature coolant circulation pump adopts air-cooled fully closed compressor refrigeration, microcomputer intelligent control, automatic opening of refrigeration system, delay closing, overheating, overcurrent multiple protection devices.

2, the circulating pump can output the cold liquid in the tank, cool or constant temperature outside the experimental container or establish a second constant temperature field.

3, the microcomputer is equipped with a timing shutdown function, after opening this function, you can set a timing shutdown time within 0-100 hours.

4, the use of double Windows, red, green two color LED display temperature set value and temperature measurement value, the quantitative resolution of 0.1℃, microcomputer can correct the deviation of temperature measurement value, so that the digital display accuracy of ±0.1℃.

5, with microcomputer software lock function, can lock the system parameters set values, irrelevant personnel can not change the set parameters.

6, all the above operations can be completed by pressing the touch key on the microcomputer intelligent control instrument, and the operation is simple.

7, the product is easy to use, can work continuously.

8. DL series low-temperature coolant circulating pump adopts air-cooled fully enclosed compressor refrigeration and microcomputer intelligent control system to provide low-temperature circulating cooling water (liquid) flow or low-temperature constant temperature water (liquid) flow. To meet the needs of cooling water and low temperature liquid to cool or constant temperature instruments (such as rotary evaporator, fermenter, electron microscope, low temperature chemical reaction kettle, electron spectrometer, mass spectrometer, density meter, freeze drying instrument, vacuum coating instrument, etc.).

9. The sink of DL series products is made of stainless steel material, and high-quality pure water can be added in the sink in advance to circulate and cool inside and outside the machine, so as to ensure the normal operation of precision instruments with high water quality requirements and extend the service life of precision instruments.

10, DL series of low temperature coolant circulation pump and 2 liters ~50 liters rotary evaporator (dish) supporting use can replace tap water condensation, especially suitable for low boiling point or heat sensitive material evaporation condensation water.

11, DL series of low temperature coolant circulation pump in the working cold tank, can also be put into a variety of containers with biochemical reagents or samples to be tested directly for low temperature constant temperature test or test.
